Cross-species summary: Horns are paired appendages with a bony core that is attached to the skull and a keratin outer sheath. There is substantial variation in the extent of horn growth, making classification difficult. However, in general, the presence or absence of horns can be attributed to the action of two alleles at an autosomal locus. The type of gene action varies considerably between and among species. Absence of horns is called 'polled'. See also entries for 'scurs'.
Have human generated variants been created, e.g. through genetic engineering and gene editing
